The factor about expertise is that it retains advancing. Simply ten years in the past, your Nokia Razor had a cool new function – SMS. Know-how trickles, and now your telephone is a “smartphone”, which is actually a handheld laptop with a digital camera virtually higher than your Nikon DSLR and a microphone that rivals newbie studio mics. Identical to your telephone, electrical muscle stimulators EMS have come a good distance because the TENS unit was first launched in 1974. EMS has change into more and more fashionable in the previous couple of years with manufacturers like Compex, the MarcPro, and Powerdot dropping into the useful health scene, serving to useful and aggressive athletes optimize coaching outcomes. However how totally different is electrical muscle stimulation than a transcutaneous electrical nerve stimulator? We’re going to speak about variations, similarities, and whether or not try to be spending that onerous earned cash on a TENS or EMS.
Transcutaneous electrical nerve stimulation (TENS) is a non-invasive pain-relief approach. A small handheld gadget, often called a TENS unit, admits low present electrical stimulation by way of skinny wires related to adhesive pads often called electrodes. These electrodes adhere to the pores and skin sending alerts that may interrupt the interpretation of ache alerts.
EMS or electrical muscle stimulation is a method generally utilized by bodily therapists and health fanatics. Just like the TENS unit, EMS is a small handheld gadget, that admits electrical present by way of skinny wires and electrodes. A key totally different is that EMS is utilized to particular muscle teams to assist with the train restoration course of or rehabilitation. EMS sends a stronger electrical present than a TENS unit and isn’t used for remedy of publish surgical ache, power ache, or wound websites.
Each TENS models and EMS function on the identical precept {of electrical} present. Compex for instance, makes use of transcutaneous electrical nerve stimulation of their gadget the Compex Edge 3.0 to electrically stimulate the muscle tissue. PowerDot markets their Powerdot 2.0 as greater than a TENS gadget combining the effectiveness of TENS and NMES or neuromuscular electrical stimulation.
The largest distinction between a TENS and EMS is within the person interface. In contrast to a TENS unit EMS units include an app which may present extra detailed analytics and utilization experiences on efficiency and restoration. Apps additionally present extra entry to controlling your gadget, For instance, Powerdot EMS is managed by way of their app, as an alternative of offering a handheld unit.
EMS units use totally different modes or packages and are engineered with extra options marketed to assist athletic efficiency outcomes corresponding to power, endurance, and restoration. {The electrical} sign triggers repeated or patterned contractions of the muscle tissue used to jumpstart the muscle fibers and practice them for a selected intent or perform, lowering fatigue, optimizing muscle restoration, and lowering ache.
This additionally accounts for the staggering distinction value between a TENS and EMS, $19.99 vs $350.
Admittedly, EMS units like Compex and PowerDot are marketed as an elite athlete restoration software. A TENS unit is just not. It’s utilized by physicians in ache administration, chiropractors, and bodily therapists to assist with ache administration, not with athletic efficiency.
The analysis on electrical stimulators could be very combined and conflicting. TENS models are indicated as a noninvasive, nonpharmacological intervention that prompts a fancy neuronal community to scale back ache by activating descending inhibitory methods within the central nervous system to scale back hyperalgesia. Basically, {the electrical} stimulation blocks the interpretation of ache alerts when the sensory neurons interpret the stimulation in a selected space of ache.
This will present some non permanent aid; nonetheless long-term efficacy is just not properly established. Efficacy is dose dependent, that means that depth or dose of stimulation is a important consider TENS software. Excessive frequencies and stronger stimulation can oftentimes exacerbate signs whereas decrease intensities are ineffective. Within the final decade there have been various systematic evaluations/meta-analyses which have examined efficacy of TENS for ache discount in folks with ache, some displaying efficacy whereas others displaying none.
Since each EMS and TENS obtained FDA approval in 2021, these units have change into broadly accessible to the general public, versus solely having prior entry to them with a prescription.
So can EMS units and TENS assist with muscle restoration, power, and scale back muscle fatigue? That’s nonetheless but to be decided. Research have proven nonetheless, that TENS will help with a selected indication of treating power or acute ache for quickly aid. Conventional TENS models function with fixed electrical stimulation, giving the person the flexibility to regulate frequency and pulse width. EMS units using TENS expertise, ship stimulation in particular patterned contractions, using totally different modes and packages. General, each TENS and EMS units will help scale back power or acute ache and assist with non permanent aid. Nonetheless using these units with a selected indication to assist improve athletic efficiency will nonetheless require extra human scientific trials to find out their efficacy as an ergogenic support.
